How to move branch from one repository to another

Question

I created a new Repository (named repoN) with the existing one (named repoE), simply by copying code from the branch (named B22).

After that, I created a new branch in repoN (named BR01). Now I made some changes in the branch (named BR01) which exist in repoN repository.

I just want to take all those changes into the old repository repoE without loosing history of BR01 into B22.

I am using SourceTree because I'm new in Git and don't know much commands.

At first you need to add to git your destination repository, lets call it repoE ( set remote tracking )

git remote set-url repoE https://github.com/USERNAME/repoE.git

then switch to branch your want to push, assume your branch called BR01

git checkout BR01

and push this branch to destination repository

git push repoE BR01
